Yes, I think Sapphire has a full-ATX board with integrated ATI graphics. I know for certain their parent company does. ECS might too, they have the Intel version so why not the AMD version?
These boards don't interest me much, so I don't remember model numbers.
Graphics wise, nVidia is fine on computer standards, but their S-Video sucks. As for performance otherwise, it's roughly the same level as the ATI solution.
